Update app open/close animations.

- For app open, the icon text remains where it is and only the icon moves.
- Similarly for app close, the icon text remains where it is and fades in
  with the rest of the other icons text.

- With this change, the original view is always "VISIBLE"
  (if BubbleTextView/FolderIcon) but we hide certain elements.

Added video to bug.
